HORSE-HOOP LEVEL-GAGE- Specification of Letters Patent.

Patented Oct. 2, 1906.

Application filed January 29, 1906. Serial No. 298,404.

To all whom it may concern.-

Be it known that I, AUeUsT HOLM UIsT, a citizen of the United States of America, residing at Bridgewater, county of Plymouth, in the State of Massachusetts, have invented certain new and useful Improvements in Horse-Hoof Level-Gages and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to horseshoers gages.

The object of my invention is to provide a gage by the use of which may be determined the height, the pitch, and the level of the under side of the hoof.

A further object of my invention is to provide such an instrument with a swiveled connection, so that the height and pitch of the sides of the hoof may be determined without removing the instrument from the hoof.

A further object is to provide a beveled protractor which is swiveled to and detachable from the base portion of the instrument.

A further object is to provide a supporting member for the gage which is detachable, so that various sizes of plates may be used to suit different sizes of hoofs.

A further object is to provide means for slidably supporting a straight-edge and a pro tractor-bar, so that they may be adjusted to various sizes of hoofs; and my invention consists of the construction, combination, and arrangement of parts, as herein illustrated, described, and claimed.

In the accompanying drawings, forming part of this application, I have illustrated one form of embodiment of my invention,

in which drawings similar reference characters designate corresponding parts, and in which Figure 1 is a side elevation of the instrument, showing its application to the hoof of a horse. -Fig. 2 is a bottom plan view of the instrument. Fig. 3 is a plan view of a supporting-spider. Fig. 4 is a side and front elevation of a screw adapted to lock the protractor-bar. Fig. 5 is a side elevation and top plan of a sleeve adapted to cooperate with a screw to lock the protractor-bar in position. Fig. 6 is an edge elevation and bottom plan view of a locking-nut. Fig. 7 is a side and front elevation of a screw adapted to receive the slidable straight-edge used in the section through the base-plate of the instrument, taken approximately on line 9 9 of Fig. 2. Referring to the drawings, 1 designates a plate having a continuous peripheral flange 2 on its under side. For varying sizes of hoofs the plate 1 may be made of different sizes; but of whatever size made each plate is provided with a plurality of openings 3 relatively of the same distance apart in each plate.

Carried by the plate 1 is a supportingspider 4, the legs of which are each provided with a lug or pin 5, adapted to engage in the openings 3 when a slight pressure is put on the spider, and when the pressure is removed the contractile force of the spider forces its lugs 5 against the walls of the openings 3 to hold the spider 4 in position on the plate. 7 5

The spider 4 is provided with a central opening 6, through which is disposed a bolt 7, having a head 8 adapted to hold the same on the spider. The opposite end of the bolt 7 is provided with screw-threads 9, and intermediate of its ends the bolt is provided with a longitudinal recess 10. Rotatably disposed on the bolt 7 is a sleeve 11, provided with a longitudinal slot or recess 12. Disposed on the bolt 7 is an interiorly-screw-threaded nut 13, provided with a milled outer edge 14, whereby the sleeve 1 1 may be forced upward on the bolt. Disposed through the slot 12 and lying within the recess 10 is a slidable removable bar 15, provided at its outer end with a plate 16, having graduations 17 thereon, marking the degrees from a horizontal plane. The protractor-bar 15 being disposed in the recess 10 of the bolt and the sleeve 1 1 being disposed on the bolt so that its slot engages over the bar 15 by tightening the nut 13 the sleeve 1 1 .will be forced against the under side of the bar, and its upper surface will be forced against the wall of the slot 10, whereby said bar 15 may be locked in a plurality of positions. This construction permits the bar to swing in a horizontal plane, the bolt 7 serving as a pivotal point. By loosening up the nut 13 the bar and its connecting parts may be entirely removed from its connection with the plate 1.

Projecting through the bar 15 adjacent the plate 16 is a bolt 18, provided with a transverse slot 19 and provided with screw-threads 20 at one end. Disposed on the bolt 18 is a plate 21, provided with an opening 22 of a diameter slightly larger than the diameter of the bolt, so that said plate may slide thereon. Provided in one face of the plate is a recess 23, and disposed on the screw-threaded end of the bolt 18 is a milled nut 24. Slidably disposed in the recess 19 of the bolt 18 and the recess 23 of the plate 21 is a straight-edge 25, provided with graduations 26, commencing at its upper end and increasing downwardly. By tightening up the nut 24 the plate 21 is forced against the straightedge which is carried in the slot 19, so that the straight-edge may be locked in a plurality of positions with relation to its length. At the same time the straightedge 25 may ,be swung through a circle, the bolt 18 forming a pivotal point therefor. 1

To ascertain the pitch and height of the front portion of a hoof, the instrument is used as illustrated in Fig. 1. To ascertain the pitch and height of the side or rear portions of a hoof, the protractor-bar is swung on its pivotal support until the straight-edge 25 rests at the desired point, the pitch being in dicated by the graduations l7 and the height being indicated by the graduations 26.

The spider 4 being held in position on the plate 1 by spring-pressure, any number of sizes of plates 1 may be used with the remainder of the instrument. The protractorbar being readily removable from its support, the instrument may be used without the use of the plate 1. The straight-edge 25 being held as described may be also readily detached from the remainder of the instrument.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is
